A & a Case Reports
|July 15, 2015
Summary
This case report details a rare intimo-intimal intussusception of the aorta. Early diagnosis and surgical intervention led to a positive outcome, highlighting the importance of timely management for this critical condition.
Area of Science:
- Cardiovascular Surgery
- Aortic Diseases
- Vascular Imaging
Background:
- Type A aortic dissection is a life-threatening condition requiring prompt management.
- Intimo-intimal intussusception is a rare complication of aortic dissection, often associated with poor prognosis.
- Fewer than 20 cases of intimo-intimal intussusception have been reported since 1962.
Observation:
- A case of type A aortic dissection with repeated retrograde intussusception of the intimal flap through the aortic valve was observed.
- Diagnosis was challenging due to the rarity of the condition and potential for delayed identification.
- Preoperative computed tomography (CT) and intraoperative transesophageal echocardiography (TEE) were crucial for accurate diagnosis and surgical planning.
Findings:
- The intimal flap intussuscepted retrograde through the aortic valve, presenting a unique surgical challenge.
- Early and accurate diagnosis facilitated timely surgical intervention.
- The patient achieved a positive outcome following surgical management.
Implications:
- This case underscores the importance of considering intimo-intimal intussusception in the differential diagnosis of complex aortic dissections.
- Advanced imaging modalities like CT and TEE are vital for diagnosing and managing this rare complication.
- Prompt diagnosis and intervention can significantly improve outcomes for patients with intimo-intimal intussusception.

01:15Aortic Regurgitation I: Introduction
1.3K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
927
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:27Mitral Valve Prolapse I: Introduction
946
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
